To investigate whether both the sources of visual information tau cue and depth cue were utilized to guide braking, in the present study we used the virtual reality technology which could decouple the dilation rate of visual object and depth cue. Participants were instructed to park a car to an obstacle as closely as possible and avoid making collision. Results showed: (1) on the condition of same initial distance from car to an obstacle, participants tended to brake in advance on tau speed-up condition, which caused longer distance from braking to an obstacle than on control condition(tau and depth cue couple);While participants tended to postpone braking on tau speed-down condition, which caused the shorter distance from braking to an obstacle than on control condition; (2) On tau speed-up and tau speed-down condition, participants automatically fine-tuned the actual braking position to avoid making collision. These results suggested that both tau cue and depth cue were processed and utilized to direct the behavior of braking by our visual perceptual system.

In order to use virtual reality as a sport analysis tool, we need to be sure that an immersed athlete reacts realistically in a virtual environment. This has been validated for a real handball goalkeeper facing a virtual thrower. However, we currently ignore which visual variables induce a realistic motor behavior of the immersed handball goalkeeper. In this study, we used virtual reality to dissociate the visual information related to the movements of the player from the visual information related to the trajectory of the ball. Thus, the aim is to evaluate the relative influence of these different visual information sources on the goalkeeper's motor behavior. We tested 10 handball goalkeepers who had to predict the final position of the virtual ball in the goal when facing the following: only the throwing action of the attacking player (TA condition), only the resulting ball trajectory (BA condition), and both the throwing action of the attacking player and the resulting ball trajectory (TB condition). Here we show that performance was better in the BA and TB conditions, but contrary to expectations, performance was substantially worse in the TA condition. A significant effect of ball landing zone does, however, suggest that the relative importance between visual information from the player and the ball depends on the targeted zone in the goal. In some cases, body-based cues embedded in the throwing actions may have a minor influence on the ball trajectory and vice versa. Kinematics analysis was then combined with these results to determine why such differences occur depending on the ball landing zone and consequently how it can clarify the role of different sources of visual information on the motor behavior of an athlete immersed in a virtual environment.

Virtual reality technology (VR) is a comprehensive technology that allows you to immerse a person in an immersive virtual world using specialized devices (virtual reality helmets). Virtual reality provides a complete immersion in the computer environment surrounding the user and responding to his actions in a natural way, manipulating objects and programmable events in the virtual environment. Virtual reality constructs a new artificial world transmitted to man through his sensations: vision, hearing, touch and others. A person can interact with a 3D, computerized environment, as well as manipulate objects or perform specific tasks by gaining user experience. Virtual reality is an evolving technology for the transfer of user experience (User Experiment: UI) from person to person. Currently, at the stage of information systems design, the use of induced virtual environment technology in dynamic interaction systems leads to the need to analyze the effectiveness of visual perception and transfer to the human neocortex. Visual perception represents a fundamental scientific task and is studied in many areas of science: neurophysiology, psychophysics, psychology, computer graphics and virtual environment, computer vision, computer science theory.

The adoption of virtual reality in manufacturing system simulation had proved its effectiveness in bridging up to the gap between different areas of expertise, especially in product design and manufacturing. Virtual reality had enclosed human–machine interface by enabling the user to be immersed into the virtual environment and experience real-time interaction with the virtual objects. In this article, an implementation of virtual reality in cellular manufacturing system simulation is presented. By utilizing the features of visualization and real-time interaction of virtual reality technology, the manufacturing process of a product had been visualized while the real-time control on the product traveling path based on the user’s input was performed and the corresponding activities that related to the change of traveling path had been predicted in the virtual environment. Through the study, simulation of the manufacturing system in virtual reality showed its potential as a powerful decision support system in process planning and scheduling. Various process planning and schedules can be planned through the virtual environment, while the product traveling distance can be obtained from the developed system.
